/**
 * Regression tests for bug #1906
 *
 * Local installs must anchor hook command paths to $CLAUDE_PROJECT_DIR so
 * hooks resolve correctly regardless of the shell's current working directory.
 *
 * The original bug: local install hook commands used bare relative paths like
 * `node .claude/hooks/gsd-context-monitor.js`. Claude Code persists the bash
 * tool's cwd between calls, so a single `cd subdir && …` early in a session
 * permanently broke every hook for the rest of that session.
 *
 * The fix prefixes all local hook commands with "$CLAUDE_PROJECT_DIR"/ so
 * path resolution is always anchored to the project root.
